Struct Lines 

pub struct Lines {
    pub contrast: f32,
    pub dark: f32,
}

Which pixels of the art are its dark lines: an opaque art pixel (before enlarging) that is contrast darker than the brightest of its eight neighbours, or at most dark bright. A see-through neighbour counts as white, so a figure’s dark outline is a line; past the picture’s edge there are no neighbours. Brightnesses are 0 to 1, read before the curve.

Fields

contrast: f32

How much darker than its brightest neighbour a line pixel is.

dark: f32

The brightness at or below which a pixel is a line anyway.
